Abstract Background Swyer syndrome (Pure gonadal dysgenesis, 46 XY) is a rare form of disorder sexual development. These patients presented with external female phenotype, normal Mullerian structures and streak gonads. Pure XY are more likely to develop germ cell tumors due the presence Y chromosome. Case presentation A 19-year-old patient phenotype primary amenorrhea. Clinical examination, Kar...

We would like to make some comments about the article “Persistent mullerian duct syndrome: a rare entity with a rare presentation in need of multidisciplinary management” (1). The authors report a DSD case diagnosed as PMDS and review some clinical aspects of this exceedingly rare syndrome, but some unclear aspects are notable. The patient described seems to be a case of ambiguous genitalia (pr...

The Future Internet of things will consist of smart objects that will form distributed and autonomous peripheral wireless networks near the user end. The distributed nature of smart object networks, also termed ad hoc networks, require novel cooperative effective and efficient protocols for dynamic environment. It is therefore very important to provide a unified flexible framework for Ad hoc sm...

background: in vivo dosimetry is a method for estimation of overall error in the delivered dose to the patients at the end of radiotherapy process. in this research, two methods for target dose calculation were evaluated on midline and central axis of photon beams in in vivo dosimetry of thorax fields. materials and methods: entrance and exit doses for anterior and lateral fields of thorax were...

Introduction Computed Tomography scans are a very important tool for diagnosis and assessment of response to treatment in the practice of medicine. Ionizing radiation in medical imaging is undoubtedly one of the most powerful diagnostic tools in medicine. Yet, as with all medical interventions, there are potential risks in addition to the clear potential benefits. Materials and Methods Two refe...

objective: acute inflammatory demyelinating peripheral neuropathy (guillain-barre-syndrome) is by far the most common cause of immune-medicated peripheral nervous system disease in children; with the near disappearance of poliomyelitis, gbs is responsible for the great majority of cases of acute flaccid paralysis. so far, in several controlled studies, corticosteroids, plasmapheresis and ivig h...

PURPOSE To image the abdomen of a patient with a gantry mounted imaging system of a linear accelerator, different cone beam computed tomography (CBCT) protocols are available. The whole-body dose of a full rotation abdomen CBCT and a half rotation CBCT was compared. In our clinic, both CBCT protocols are used in daily routine work. METHODS With an adult anthropomorphic Alderson phantom, the w...

The impact of PGF2? on total proteins, free amino acids and the amino transferases in the gonads of silkworm, Bombyx mori L. were investigated in the present experiment. The effect of PGF2? resulted in increase in the total protein and free amino acid contents in the gonads of silkworm larvae indicating improved structural and dynamic levels of organization. The enhanced activity levels of amin...
